# 2. Basic Output (The "Hello World" program)

In Perl we use the `print` command to echo strings and expressions to the screen.

The neophyte "Hello World!" program can be written in perl as follows:

    print "Hello, World!\n";

Now here's some explanation (in case you need any):

1. The string is enclosed in double-quotes(`" ... "`) because that's how string constants are represented in perl.
2. `\n` is a special character that is called "newline". When you print a newline you will see that your output started on a new line.
3. The semi-colon (`;`) at the end indicates that this is the end of a perl command. Every perl command should be terminated with a semicolon.
